Cytology canine transitional cell

How do you diagnose TCC in dogs?
Generally this includes a complete physical exam, CBC (complete blood cell count), blood chemistry, urinalysis, thoracic radiographs (chest X-rays), abdominal ultrasound, and a urine culture.
Diagnosis of TCC is typically made with either urine cytology or a tissue biopsy sample, often collected by cystoscopy..

What are transitional cells in dogs?
Transitional cell carcinoma (TCC), also referred to as urothelial carcinoma, is the most common form of urinary bladder cancer in dogs, affecting tens of thousands of dogs worldwide each year.
Canine TCC is usually a high grade invasive cancer..
What causes TCC in dogs?
The exact cause of TCC in an individual dog is usually not known.
In general, canine TCC results from a combination of several factors including genetic predisposition and environmental factors.
A genetic predisposition is strongly suspected because TCC is more common in specific breeds of dogs..
What is transitional cell carcinoma bladder cytology dog?
A non-invasive test for TCC has been validated for dogs.
It turns out that 85 percent of canine transitional cell carcinomas have a specific mutation in a gene called BRAF.
This mutation can be detected in a urine sample, sometimes well before the tumor is visible via the special imaging described..

Any damage that results in a separation (desquamation) of the surface cells of the renal pelvis, ureters, bladder or first segments of the urethra will lead to a high number of transitional cells in the urine specimen (urothelial polyp, tumour or cancer, usually of the bladder).
Cystoscopy is the method of choice for evaluation of the primary tumor in patients with bladder carcinoma.
Transitional cells are able to change shape and stretch.
They make up the lining of the renal pelvis, ureters, bladder and urethra.
The lining of these organs need cells that can stretch to expand when urine is stored in or flows through them.

Canine TCC is typically a disease of older female dogs, although males can be affected. Scotties, Shetland sheepdogs, West Highland white terriers, Airedale

Can a cadet BRAF test detect transitional cell carcinoma in dogs?

The CADET BRAF Mutation Detection Assay is also now available to detect a common genetic mutation in dogs with transitional cell carcinoma; this test is performed on urine that can be collected at home and submitted to a lab for analysis.
A positive result is highly specific for a diagnosis of transitional cell or urothelial carcinoma.

Diagnosis

As would be expected, the most common clinical signs are stranguria, hematuria, dysuria and pollakiuria.
Rarely is the presenting sign lameness, secondary either to hypertrophic osteopathy or bone metastasis.
A tentative diagnosis can be made via identification of a bladder (Photos 1 and 2) or urethral mass (Photo 3) on ultrasound or other imaging,.

Do female dogs get more transitional cell carcinoma?

We know that female dogs tend to get more transitional cell carcinomas than male dogs, possibly because females do less urine marking and are thus possibly storing urinary toxins longer.
In cats, however, males have an increased risk over females.

Etiology

There appear to be both genetic and environmental risk factors for the development of TCC in dogs.
In humans, cigarette smoking, exposure to chemicals, use of select medications and chronic inflammatory conditions of the bladder have been associated with an increased risk of bladder tumors.
Previous studies have found that dogs exposed to insectici.

Is blind cystocentesis a risk factor for TCC in dogs?

In middle age to older dogs of breeds with high risk of TCC, it is appropriate to evaluate for TCC on initial presentation.
Furthermore, blind cystocentesis is associated with risks of seeding the malignancy along the needle tract.

Treatment Options

1.
Surgery:Given the size and location of these tumors, surgical intervention often is not an option.
Tumors in the apex are more amenable to surgical resection; however, there is still a high risk of local recurrence and/or distant metastasis so that surgery is not likely to be curative.

What is invasive transitional cell carcinoma (TCC) in dogs?

Invasive transitional cell carcinoma (TCC) is the most common form of canine urinary bladder cancer affecting tens of thousands of dogs worldwide each year, and the prevalence appears to be on the rise.
Most TCCs are intermediate to high-grade papillary infiltrative tumors; superficial, low-grade tumors are uncommon.
